1. Impact of adhesive and photoactivation method on sealant integrity and polymer network formation
We evaluated the influence of photoactivation method and hydrophobic resin (HR) application on the marginal and internal adaptation, hardness (KHN), and crosslink density (CLD) of a resin-based fissure sealant. Model fissures were created in bovine enamel fragments (n = 10) and sealed using one of the following protocols: no adhesive system + photoactivation

3. Effect of addictives on crystallization of ice cream. / Efeitos de aditivos na cristalizaÃÃo de sorvetes
The present study aimed to evaluate the influence of addition of carrageenan and calcium on the process of ice recrystallization in the ice cream mass. A basic mixture was prepared and divided into two parts; to one of them, carrageenan was added to attain the proportion of 0,05 percent of the total volume. Subsequently, each one of the two parts were subdiv

4. Influencia de irrigantes endodonticos na resistencia de união de um adesivo autocondicionante a dentina da camara pulpar
Chemical irrigants and medications used in endodontic therapy may have an adverse effect on bonding to pulp chamber dentin. The aim of this study was to evaluate in vitro the influence of endodontic irrigants on the bond strength of a self etching adhesive system to bovine teeth pulp chamber dentin. Seventy crowns of bovine mandibular incisors were cut to ex

5. Study of the stability of sliced cooked ham in modified atmosphere. / Estudo da estabilidade de presunto cozido fatiado em atmosfera modificada.
The purpose of this study was to evaluate the efficiency of packaging systems with modified atmosphere to preserve the quality of sliced cooked ham. Thus the quality stability of the product at 4 +/_:t 1°C, packed in a gas barrier package with three kinds of modified atmosphere (100% CO2, 60% CO2/40% N2 and 25% CO2 I 75% N2), was studied. The shelf-life of

6. Calcium Transport in Sealed Vesicles from Red Beet (Beta vulgaris L.) Storage Tissue 1: II. Characterization of 45Ca2+ Uptake into Plasma Membrane Vesicles
Calcium uptake was examined in sealed plasma membrane vesicles isolated from red beet (Beta vulgaris L.) storage tissue using 45Ca2+. Uptake of 45Ca2+ by the vesicles was ATP-dependent and radiotracer accumulated by the vesicles could be released by the addition of the calcium ionophore A23187. The uptake was stimulated by gramicidin D but slightly inhibited

7. Calcium Transport in Sealed Vesicles from Red Beet (Beta vulgaris L.) Storage Tissue 1: I. Characterization of a Ca2+-Pumping ATPase Associated with the Endoplasmic Reticulum
Calcium transport was examined in microsomal membrane vesicles from red beet (Beta vulgaris L.) storage tissue using chlorotetracycline as a fluorescent probe. This probe demonstrates an increase in fluorescence corresponding to calcium accumulation within the vesicles which can be collapsed by the addition of the calcium ionophore A23187. Calcium uptake in

8. New approach to the cultivation of methanogenic bacteria: 2-mercaptoethanesulfonic acid (HS-CoM)-dependent growth of Methanobacterium ruminantium in a pressureized atmosphere.
The sensitivity of the requirement of Methanobacterium ruminantium strain M1 to a new coenzyme, 2-mercaptoethanesulfonic acid (HS-CoM) was examined by use of new techniques that were developed for rapid and efficient handling of large numbers of cultures of methanogenic bacteria. The system uses sealed tubes that contain a gas mixture of 80% hydrogen and 20%

9. Inhibition of Listeria monocytogenes by Lactobacillus bavaricus MN in beef systems at refrigeration temperatures.
The ability of Lactobacillus bavaricus, a meat isolate, to inhibit the growth of three Listeria monocytogenes strains was examined in three beef systems: beef cubes, beef cubes in gravy, and beef cubes in gravy containing glucose. The beef was minimally heat treated, inoculated with L. bavaricus at 10(5) or 10(3) CFU/g and L. monocytogenes at 10(2) CFU/g, va
